The car radio became indispensable for the driver as the passenger. It is indeed the ideal companion who makes you the conversation, informs you and fills you with its shows, its music and its melodies, making the road less long, the journey less strenuous and the lively journey, keeping the senses awake, the eye riveted on the road. It is indeed difficult to do without it, especially since it has evolved, offering more aesthetics and features. In addition to dissipating boredom and delaying fatigue, it periodically gives you the weather report and the information you need to tag your course, not to mention GPS and other technological possibilities.

This sound system as well as visual is now installed in any kind of motor vehicle, it is not only found by car, but also by bus, by truck, by boat, even on a tractor and other agricultural or construction equipment. It helps the driver and passengers to relax listening to music and radio broadcasts.

The first Autoradio receiver, the autosuper AS5 of Blaupunkt, was put up for sale from 1932. Originally, it was only a simple cubic-shaped box attached to the dashboard, it just allowed to adjust the volume and search the autoradio gps french} station manually by means of a rotary knob. The tuning frequencies of the receiver, (large waves, small waves and subsequently the FM waves) were indicated on a graduated dial. The appearance of the transistor and its generalization have immediately contributed to the success of the car radio by allowing it to perfect itself even more. This is also due to two techniques that have come in addition to this already performing ensemble, this is the diffusion in frequency modulation (FM Radio) and the integration of the cassette player, which offered the possibility to choose his music to The user. In this way, the car radio will quickly become a handset, associating the radio station with the tape recorder, which will be reinforced with the development of the stereo, allowing the connection and amplification to four loudspeakers (two at the front and two at the back of the (vehicle), this system would hold the course until the invention of the compact disc (CD) towards the end of the 1980 decades.

The standard car Radio installation

Over time and from the years 1960 and 1970, the cars of any brand reserve a particular location to the car radio on their dashboard. Vehicles that do not have a dedicated location can install the accessories under their dashboard or in a central console. The expansion of electronic models, without potentiometers, allows easier mounting. This gives rise to a first standardisation in a form called Din, or simple din, offering a height of 50 mm thickness on the dashboard, which will become the ISO 7736 standard. It is therefore possible to integrate the appropriate radio station into any vehicle with a location for that purpose. This is however the first step of the standardization, the electrical connection being of the spring of each mark. It was not until the first half of the decade 1990 to see the deployment of the second stage, with the ISO 10487 standard. From this innovation, the connections are made by means of two connectors, one for the power supply and the other for the loudspeakers, making the installation even simpler on all ranges and car brands. Some vehicle manufacturers, particularly in Japan, considered it interesting to double the surface of the car radio’s location, thus bearing it at 100 mm, the so-called “autoradio 2 din faceplate” standard, it was soon to be adopted in the United States and Europe. This democratization of large screens has comforted the trend that is spreading over all the car brands.

The car radio in the digital age

In the late 2000 and early 2010, most car radios have USB port and can play an external hard drive or SD card. Some model have even been able to integrate Bluetooth technology, making it easier to use the mobile phone according to the handsfree function, as well as playing audio files that are located on the memory of the same phone. Some models go completely from CD-deck to the benefit of a USB port, a Bluetooth connection or an SD card reader. High-end car radios are equipped with a retractable screen to play movies from a DVD player, an option only reserved for passengers in the rear of the vehicle and formally forbidden to the driver. The manufacturers have added all kinds of options to the car radio with the development of ICT (information technology and communication). An original car radio is often connected to the vehicle’s calculators, which makes it possible to install an anti-theft system that is difficult to be; It also makes it easier to display and disseminate information or alert messages. By means of the Bluetooth connection, the car radio can also connect with a smartphone or tablet to add additional features such as hand-free phone calls, audio content broadcasting or audio A GPS guide for example.

The car radio, which became indispensable for many drivers, has therefore undergone considerable evolution. It always offers more possibilities like Walkmans and other music players, which sometimes makes it very sophisticated. This is why it becomes difficult to choose a device that meets its expectations, both the proposed range is wide, ranging from the “classic” car radio to the “New generation” device.
